add icons to summaries and improve spacing

[pve-manager.git] / www / manager6 / panel / ConfigPanel.js

/*
 * Base class for all the multitab config panels
 *
 * How to use this:
 *
 * You create a subclass of this, and then define your wanted tabs
 * as items like this:
 *
 * items: [{
 *  title: "myTitle",
 *  xytpe: "somextype",
 *  iconCls: 'fa fa-icon',
 *  groups: ['somegroup'],
 *  expandedOnInit: true,
 *  itemId: 'someId'
 * }]
 *
 * this has to be in the declarative syntax, else we
 * cannot save them for later
 * (so no Ext.create or Ext.apply of an item in the subclass)
 *
 * the groups array expects the itemids of the items
 * which are the parents, which have to come before they
 * are used
 *
 * if you want following the tree:
 *
 * Option1
 * Option2
 *   -> SubOption1
 *	-> SubSubOption1
 *
 * the suboption1 group array has to look like this:
 * groups: ['itemid-of-option2']
 *
 * and of subsuboption1:
 * groups: ['itemid-of-option2', 'itemid-of-suboption1']
 *
 * setting the expandedOnInit determines if the item/group is expanded
 * initially (false by default)
